Explain the following reaction.
Silicon dioxide is treated with hydrogen fluoride.
थोडक्यात उत्तर
उत्तर
When silicon dioxide (SiO2) is heated with hydrogen fluoride (HF), it forms silicon tetrafluoride (SiF4). Usually, the Si–O bond is a strong bond and it resists any attack by halogens and most acids, even at a high temperature. However, it is attacked by HF
\[\ce{SiO_2 + 4HF -> SiF_4 + 2H_2O}\]
The SiF4 formed in this reaction can further react with HF to form hydrofluorosilicic acid.
\[\ce{SiF_4 + 2HF -> H_2SiF_6}\]
